Vulnerability from fkie_nvd - Published: 2024-05-03 02:15 - Updated: 2025-08-06 14:24
Severity ?
6.8 (Medium) - CVSS:3.0/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
TP-Link Archer AX21 tmpServer Command 0x422 Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer AX21 routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of command 0x422 provided to the tmpServer service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-19905.

Se requiere autenticaci\u00f3n para aprovechar esta vulnerabilidad. La falla espec\u00edfica existe en el manejo del comando 0x422 proporcionado al servicio tmpServer. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un b\u00fafer basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto de la ra\u00edz. Era ZDI-CAN-19905."
